Abstract

There is provided a thin transformer capable of being used in a thin display device such as a liquid crystal display (LCD) device and a light emitting diode (LED) display device. The transformer includes: a bobbin part including a plurality of bobbins, each including a pipe shaped body part having a though-hole formed in an inner portion thereof and a flange part vertically protruding outwardly from both ends of the body part; a core inserted into the through-hole of the bobbin to thereby form a magnetic path; and a coil part including coils each wound around the plurality of bobbins, wherein the bobbin part includes an outer bobbin and an inner bobbin inserted into the through-hole of the outer bobbin to thereby be coupled thereto, and the flange part of the bobbin part includes at least one insulating rib protruding from an outer surface thereof in order to reinforce strength thereof.

Description

technical field [0001] The invention relates to a thin transformer applicable to thin display devices such as LCD display devices and LED display devices. Background technique [0002] In recent years, in the display industry, flat panel displays (FPD: Flat Panel Display), a new technology suitable for multimedia systems with high resolution and large screens, have attracted attention instead of CRT (Cathode Ray Tube: Cathode Ray Tube). [0003] In particular, among large displays, thin displays such as LCD (Liquid Crystal Display) TV and PDP (Plasma Display Panel) TV are attracting attention, and it is expected that they will continue to attract attention in terms of price and market prospects in the future. [0004] Among them, LCD TVs have used cold cathode fluorescent lamps (CCFL: Cold Cathode Fluorescent Lamp) as the backlight until now, but recently, LED (Light Emitting Diode) has been adopted in consideration of various advantages in terms of power consumption, lifesp...
